Porter's patent "relates to a machine or apparatus in which cloth or other kind of fabric can be measured while being wound upon a roller. The board forming the center of a bolt of cloth or other fabric is clamped endwise between two aligned and axially-adjustable rotary shafts, and as the cloth unwinds it passes over a reel, by which its length is measured, and is wound upon a roller arranged parallel to the reel." (Patent Number 194,462)
